Florel ® can also be sprayed at 350–400 ppm early in the crop cycle, especially for larger pots and baskets, to improve branching and control growth. Do not spray Florel ® on stressed plants. A very low rate Bonzi ® drench (0.05 ppm) can be used at the end of production to hold and tone plants before sale.
